Application filed October 30, 1916. Serial No. 128,519.

To all, whom it may concern:

Be it known that we, LEROY H. NAZER and JAMES L. JENSEN, citizens of theUnited States, both residing at Cowley, in the county of Big Horn andState of Wyoming, have invented certain new and useful Improvements inEndless Sickles, of which the following is a specification.

This invention relates to, cutting mechanisms for use in connection withagricultural machines.

The object of the present invention is to provide a cutting mechanismwhich may be readily attached to any agricultural machine, the saidcutting mechanism being in the form of an endless belt, thereby doingaway with the vibration and noise usually found in the reciprocatingtype cutter.

With this and other objects in view the invention consists of a cutter,a chain operating within said bar and carryin knives, sprockets engagingsaid chain, an means for imparting mot1on to the said sprockets.

In the drawing Figure 1 is a plan view-of an endless cutting mechanismconstructed in accordance with the present invention;

Fig. 2 is an elevation of the same.

Fig. 3 is an enlarged transverse section looking through the cutter barand showing the endless cutting knives in position.

Fig. 4 is an enlarged view of one end of the cutter bar with the guardand knives removed.

Fig. 5 is a detailed view of the means for driving the sprockets.

Fig. 6 is a detailed view illustrating the manner of engagement of thesprockets with the links of the endless chain.

Fig. 7 is an enlarged detailed plan view of one end of the cutter bar,showing the device for separating the hay.

Fig. 8 is an enlarged detailed elevation of one of the sprockets.

Fig. 9 is an enlarged plan view of a portion of the chain and knives,the upper flight of the chain being shown in full lines and the lowerflight in dotted lines.

Referring to the drawings the improved cutting mechanism comprises aninclosed casing open upon its front face and provided 7 with enlargedend portions which are closed,

and as arranged in the form shown in Fig. 2 and is provided with the endportions 4 and 5. Said casing is formed with a longitudinal slot 6 inwhich the endless chain which carries the cutting knives is adapted tomove. The chain which is designated as at 7 is composed of a number oflinks 8 each of the said links being provided with a slot 9 in one end,and an engaging lug 10 at its opposite end. Attached to these links bymeans of bolts or rivets 11 are angularly shaped knives .12, theseknives being provided with diagonal cutting edges 13. The cham 7 is inan endless form, and is adapted to travel back and forth within the slot6, the upper and lower flights of this chain bemg separated by a thinstrip 14.

The casing 1 is provided along its lower edge with a series of slots 15to receive lugs 16 formed on the guard 18. The rear end of this guard 18is secured to the cutter bar 1 through the medium of the bolt 19.

The chain 7 is driven by means of sprockets 20, one of these sprocketsbeing provided in each of the portions 4 and 5,

the teeth 21 of which engage slots 22 formed in each of the links 8. Oneof the sprockets 20 has secured upon its rear face a pinion 24 engagedby the pinion 25 and carried by the shaft 25, the bearings 26 of theshaft 25 bein supported upon a portion 27 of the mac ine. Upon theopposite end of the shaft 25 is a beveled pinion 28 driven by a gear 29receiving its power from a suitable source. A shield 30 is provided ,forthe sprocket and gear 28 and 29. If desired a suitable casing mayinclose the shaft 25 as shown.

The front portions 4 and 5 of the casing which inclose the sprocket 20are provided each with a cover 31 as shown. 7

The casing 1 may have secured to its en as shown a device for separatingthe standing hay, in order to let the end of the cutting mechanism pass.This device consists of a member 32 having one end secured to thecasing, its opposite end bein supported by a brace 33. The usual mole s0e 34 is shown as carried by the casing.

From the foregoing description when taken in connection with theaccompanying drawings, it will be seen that the invention provides asimple and eflicient cutting mechanism, for agricultural machines, whichwill eliminate the unnecessary jar and noise.

What is claimed is In combination with an inclosed integral casing withenlarged end portions, the front face of the casing having a recessextending intermediate said enlarged ends, sprocket wheel mounted withinsaid enlarged end positioned intermediate and below the porti ns, and anendless chain passing about fingers.
